Description

[Detailed description of the invention] Industrial applications The present invention relates to a safety device for an iron.

Conventional Structure and Seven Problems In recent years, the temperature control of irons is increasingly using electronic control, and with this electronic control, the number of safety devices that incorporate electronic control is also increasing.

Conventionally, an iron equipped with an electronically controlled safety device is equipped with a heater 2 and a thermistor 3 on the base 1 of the ironing surface, and a handle 4 of the iron is electrically connected to the thermistor 3, as shown in FIG. A connected temperature detection unit 5 and an operation detection device 6 that detects ironing operation and operation stop.
and. At the rear of the iron, the temperature detection section 6 and the detection device 6 turn on electricity to the heater.

It is provided in the control section 7 that turns off the power. The control section 7 cut off the energization circuit to the heater after a certain period of time after receiving the ironing operation stop signal from the operation detection device 6. Therefore, when the iron is not being ironed, the power to the heater is cut off to prevent fires and scorching of clothes caused by leaving the iron unattended.
- However, with the above configuration, whether the iron is laid down horizontally or in an upright position, if no ironing operation is performed, the control unit 7 cuts off the power to the heater after a certain period of time. Now, if you set the fixed time to about 1 to 2 minutes, the power circuit to the heater will be cut off during the ironing preparation work, such as standing up the iron and replacing clothes. The above problem can be resolved by setting the iron to 1 minute, but if the iron is left lying flat, there is a danger that the heating surface of the iron's Pace 1 will burn clothing or the mat, or even cause a fire. However, there were problems in terms of safety and actual usage of ironing.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned problems and provides a highly safe iron suitable for the actual use of ironing.

Structure of the Invention In order to achieve the above object, the iron of the present invention includes a detection means for detecting a horizontal state in which an ironing operation is performed and a vertical state in which the iron is left standing, and a detection means for detecting a horizontal state in which the iron is left standing. The heater circuit is configured to include a control means that cuts off the power supply to the heater circuit when a predetermined period of time has elapsed in either the application stop state or the vertical state.

According to the above configuration, the power supply to the heater circuit can be cut off in a short time when the ironing operation is stopped, and the power supply to the heater circuit can be cut off for a long time in the vertical state.

DESCRIPTION OF EMBODIMENTS An iron according to an embodiment of the present invention will be described based on the drawings. Note that the same constituent elements as those of the conventional example are given the same reference numerals.

In FIG. 1, the iron of this embodiment is equipped with a detection device 8 on the handle 4 for detecting the horizontal state in which ironing is performed and the vertical state in which the iron is left standing. A control circuit 9 is provided which controls the supply of electricity to the heater by means of a detector and a detector.

The detection device 8 will be explained with reference to FIG. In the figure, the detection device 8 consists of a cylinder 1o, an electrode part 11 provided at one end of the cylinder 1o, and mercury 12 which is a conductor movable inside the cylinder 10. The movement of the electrodes and the mercury 12 within the cylinder 10 brings the two electrodes into a conductive state and a disconnected state, and the two electrodes are each connected to a control circuit 9.

The operation of the control circuit 9 will be explained based on FIG.

Now, if the detection device 6 changes from the cut-off state to the conduction state and the conduction state continues for 11 minutes, the control circuit 9 will stop energizing the heater at that point. Further, when the detection device 6 changes from the cutoff state to the conduction state and the conduction state continues for t2 minutes, the control circuit 9 stops energizing the heater at that point.

In FIG. 4, the detection device 8 provided on the handle 4 is attached at an angle α with respect to the horizontal direction. This angle α is determined within a range in which the mercury 12 can move within the cylindrical body 10 during the ironing operation. The vertical state is a conductive state as shown in Figure 4(a), the horizontal state where the ironing operation is stopped is a disconnected state as shown in Figure 4(b), and the horizontal ironing operating state is as shown in Figure 4. As shown in (C), the conduction state and cutoff state are repeated. Therefore, when the ironing operation changes from the ironing operation to the ironing operation, that is, when the horizontal state changes from the vertical state to the vertical state, the detection device 8 changes from the cutoff state to the conduction state, and if the iron is left for t1 minutes, the control circuit automatically turns on. 9 stops energizing the heater, and if the state changes from still ironing operation state to ironing operation stopped state, the control circuit 9 stops energizing the heater after t2 minutes because the detection device 8 changes from the conduction state to the cutoff state. do. When ironing is in operation,
The detection device 8 is repeatedly cut off and turned on, and this cycle is 1. ．． Tl in advance so that it will be 12 minutes or less.

Since t2 is set, the control circuit 9 does not stop energizing the heater.

As described above, in the iron of this embodiment, if the ironing operation is stopped and left for t2 minutes, the heater power will be stopped, and if the iron is left standing for t1 minutes, the heater power will be stopped. Therefore, set tl to 10~
If you set the iron to about 15 minutes and t2 to about 1 to 2 minutes, if the iron falls over and is left unattended due to either phenomenon, i1 to 21
If you leave the iron in the outlet for about 2 minutes, the heater will stop energizing after about 10 to 16 minutes, allowing you to use it for ironing, and prevent fires and burning your clothes. .

In the above embodiment, the detection device is in the conductive state in the vertical state, but the reverse may be possible. In short, the angle at which the detection device is mounted is sufficient as long as the conductor can move within the cylindrical body in accordance with the ironing operation.

Effects of the Invention As described above, the iron of the present invention has the function of detecting the horizontal and vertical states of the iron with one detection device, and the function of detecting the ironing/stopping state. It is characterized by the ability to detect unsafe conditions, such as overturning the iron and leaving the iron unattended, and the time to cut off the heater power depending on each condition can be set arbitrarily, thereby preventing fires and scorching of clothing, etc. Moreover, it is possible to easily provide products suitable for the actual usage of ironing at low cost, and the effects are unique.
